Control Groups
The Mercury laser control system in your Skywriter HPX M-5 laser is simplified by breaking the control
up into groups relevant to different features of the system. These control groups are:
1.
Master Group
2.
Builder Main Group
3.
Color Group
4.
Intensity Effect Group
5.
Prism Control Group
6.
Geometric Pre Group (advanced builder only) and Geometric Post group
7.
Motion Macro Group (basic builder only)
8.
Wave Effect 1 group (advanced builder only)
9.
Wave Effect 2 group (advanced builder only)
10.
Motion Effect 1 group (advanced builder only)
11.
Motion Effect 2 group (advanced builder only)
The
Master Group
is the entirety of the Master Fixture and consists of the Enable function, Master
Maximum Intensity, Master X/Y scale and offset.
The
Builder Main Group
is where the gobo wheels and overall intensity controls are located in the basic
and advanced builders. There are also a few reserved channels for future expansion.
It’s important to
note the maximum intensity in this group will never exceed the Intensity set in the Master fixture.
The
Color Group
contains RGB1 and RGB2 color pickers in both builder modes, preset color macros in the
basic builder and a wide range of color tools in the advanced builder. For more information on the
different color effects possible with advanced builders, please visit

The
Intensity Effect group
is not yet active but will be pretty damn cool when it is.
The
Prism Control group
is where the digital prism and its parameters are accessed. At the time of this
writing there are 11 different digital prisms built into the system. Additional channels control the X and Y
spacing of the prisms and the rotation across the facets. The rotation parameter is an incremental
rotation applied to each successive prism element. For example, if the prism inner rotation is set to 5°,
the first element will be rotated 0°, the second 5°, the third 10°, and so on. To rotate the entire prism,
select rotation or spin from the geometric post group. To rotate the individual facets of the prism, select
rotation or spin from the geometric pre group.
The
geometric pre and post groups
are the largest departure from more traditional intelligent lighting
fixtures. The basic builder only has access to the Geometric Post group, this provides access to X and Y
scale (zoom), X and Y position (pan and tilt), Z rotation (gobo indexing) and Z Spin (gobo rotation). The
“Post” refers to these parameters happening afte
r the prism modifier. For example, with a 1x3 linear
prism on a circle gobo, a Z spin would spin the entire array of circles.
The advanced builders also permit access to the Geometric Pre group, which might at first seem
redundant, but when combined with the prism effects the Geometric Pre/Post controls enable some
very sophisticated effects that are unparalleled on any moving head. Because the Geometric Pre group
is calculated before the prisms, you can use it to move, scale, rotate or spin the individual facets of the
prism. As an example, with a 1x3 linear prism with a triangle gobo, each of the triangles in the prism can
